[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A municipal engineering construction support that is easy to disassemble, such as Figure 1-Figure 4 As shown, it includes a mounting base 1, the lower part of the mounting base 1 is rotatably connected with 4 self-locking wheels 2, the self-locking wheels 2 have a self-locking function, a hydraulic cylinder 3 is installed on the mounting base 1, and a mounting plate 5 is connected to the telescopic end of the hydraulic cylinder 3, and 4 guide columns 4 are connected to the mounting base 1, and the guide columns 4 are connected to the mounting plate 5. A supporting plate 6 is installed on the mounting plate 5, and the supporting plate 6 is a detachable connection structure. The left front side and the right rear side of the lower part of the supporting plate 6 are connected to the first limiting column 61, and the lower middle part of the supporting plate 6 is connected to A second limiting column 62 and a first threaded column 63 are connected to the left rear side and the right front side of the lower part of the support plate 6. A locking mechanism 7 is arranged on the mounting plate 5. The locking mechanism 7 includes a second threaded column 73. The right front side and the left rear side of the upper part of the mounting plate 5 are connected to the second threaded column 73. The second threaded columns 73 are contact-connected with the corresponding first threaded columns 63. A locking piece 71 is threadedly connected between the first threaded column 63 and the adjacent second threaded column 73. Four auxiliary plates 72 are connected to the outside of the locking piece 71.

[0021] like Figure 1 and Figure 5 As shown, an anti-dumping mechanism 8 is also included, and the anti-dumping mechanism 8 includes a mounting frame 81. The mounting frames 81 are installed on the left and right sides of the mounting base 1. A drill bit 82 is threadedly connected to the mounting frame 81. The lower part of the drill bit 82 is a conical structure, and the upper side of the drill bit 82 is connected to a power assist plate.

[0022] It should be noted that a tunnel is a passage dug underground or underwater, which can effectively relieve ground traffic pressure, protect the environment and improve transportation efficiency. During the tunnel construction process, a support structure needs to be established on the inner wall of the tunnel to ensure the smooth progress of the tunnel construction work. First, the device is moved to the lower part of the position that needs support using the self-locking wheel 2, and then the self-locking wheel 2 is self-locked to prevent the device from sliding. Then the power-assisting handle 83 can be turned to make the drill bit 82 move downward until it contacts the ground. The conical structure at the bottom of the drill bit 82 makes it easier for the drill bit 82 to drill into the ground and prevent the device from tipping over, thereby enhancing the stability of the device. After the device is fixed, The first limiting column 61 and the second limiting column 62 are inserted into the corresponding positions on the mounting plate 5, and the first threaded column 63 contacts the second threaded column 73, and then the auxiliary plate 72 is used to rotate the adjacent locking piece 71 between the first threaded column 63 and the second threaded column 73 and lock it, thereby preventing the support plate 6 from shaking. This method makes installation and disassembly more convenient, and is also convenient for transportation and carrying. After the support plate 6 is installed, the hydraulic cylinder 3 is turned on. The telescopic end of the hydraulic cylinder 3 drives the mounting plate 5 to move upward under the action of the guide column 4, and then drives the support plate 6 to move upward until the support plate 6 contacts and supports the inner wall of the tunnel, thereby completing the support and protection work of the inner wall of the tunnel.

[0023] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
